I’m trying to help a friend in Bosnia who has a Mazda 626 2.0 diesel (I think with 136 hp, Bj 2003 (?)). The vehicle comes from Germany and was exported a year ago. However, I don’t have the exact data yet, the mileage is about 210tsd km. Now to the problem: the car ran perfectly on the way home until before the garage gate, was briefly parked and then did not want to start. Fuel is promoted, the E Injector pump has been removed and tested at the Bosch Service, it works, the engine runs short with start pilot and then goes out again. The camshaft sensor has been renewed, the injectors have been tested and I think it is also renewed, but the engine doesn’t want to start. I don’t know about Mazda very well, but I think that it can be on the control unit as well as on the immobiliser. I don’t think he gets a diesel injection. A common mistake. The mechanics on site are at a loss, but also no Mazda connoisseurs. What happens if you build up the control unit from the weaker engine version of the diesel on the same model and install it in the defective one for test purposes? I hope for hints that I can pass on. The vehicle is of elementary importance for the owner and is now already standing since 06.10.2013.
